PrintIngress Protection
Ingress protection tells how much the structure of the Switch provides protection against solid objects and water.
1. First Digit: Protection against Solid Objects
| Code | Level of protection | |
|---|---|---|
| 0 |  |
No protection against entry of dust or dirt. |
| 1 |  |
Round test object with 50-mm diameter will only partially enter the interior. |
| 2 |  |
Round test object with 12.5-mm diameter will only partially enter the interior. |
| 3 |  |
Round test object with 2.5-mm diameter will not enter the interior. |
| 4 |  |
Test object with 1.0-mm diameter will not enter the interior. |
| 5 |  |
No dust or dirt that would affect the correct operation of the device or safety will enter the interior. |
| 6 |  |
Dust and dirt will not enter the interior. |
2. Second Digit: Protection against Liquids
| Code | Level of protection | Test method outline (test performed using pure water) |
||
|---|---|---|---|---|
| 0 | No protection | No protection against entry of water | No test | |
| 1 |
Protection against water drops  |
No harmful effects from vertical water drips | By using water drip tool vertically and dropping water for 10 min |  |
| 2 |
Protection against water drops  |
No harmful effects of water drips from vertical direction when the enclosure is tilted at 15° from its normal position | By using water drip tool, moving it at an angle of 15°, and dripping water for 10 min (2.5 min per direction) |  |
| 3 |
Protection against water spray  |
No harmful effects of water spray at any angle up to 60° from the vertical direction | By using the tool shown on the right, and spraying water vertically at angles up to 60° for 10 min |  |
| 4 |
Protection against water splash  |
No harmful effects of water splash from all directions | By using the tool shown at the right, and splashing water from all directions for 10 min |  |
| 5 |
Protection against water jets  |
No harmful effects of water jets from all directions | By using the tool shown on the right, and jetting the water from all directions to the object surfaces for 1 m2/min, for at least 3 min total. |  |
| 6 |
Protection from strong water jet  |
No harmful effects of strong water jets from all directions | By using the tool shown on the right, and jetting the water from all directions to the object surfaces for 1 m2/min, for at least 3 min total. |  |
| 7 |
Protection against submersion in water  |
No harmful effects from submersion in water to a certain level of pressure and length of time | Submerge to 1 m depth in water (when device height is 850 mm or less) for 30 min |  |
This does not imply that the device can be operated under water.
Standard switches are often IP40. Sealed switches are often IP67.
